Jim Cramer tackles the market highs and how investors should react to them, Trump's tweets about Facebook's (FB - Get Report) Libra, and what investors should watch for during Amazon's (AMZN - Get Report) Prime Day.

What's Going on in the Markets?

The market is still riding the highs from Federal Reserve Chair Jerome Powell's testimony in front of the House Financial Committee earlier this week.

"We're learning that interest rates -- that the neutral interest rate -- is lower than we had thought and I think we're learning that the natural rate of unemployment is lower than we thought," Powell said. "So monetary policy hasn't been as accommodative as we had thought."

The S&P 500 hit 3,000 on Wednesday--the first day of Powell's testimony.

Then the Dow hit 27,000 Thursday.
